Uses the random and chrono C++11 libraries to generate random values. This is simply syntatic sugar on top of the STL facilities. The generated random numbers are different for each execution thanks to a chrono-based seed.
Example:
// (1) integral function parameter within range [1 ; 6]
std::cout << randomize::rand(1, 6) << '\n';
// (2) integral random function generation within range [1 ; 6]
auto f = randomize::get_rand(1, 12);
std::cout << f() << " " << f() << " " << f() << " " << f() << '\n';
// (3) floating-point function parameter within range [3.14 ; 42]
std::cout << randomize::rand(3.14, 42.) << '\n';
// (4) floating-poing random function generation within range [-16 ; 64]
auto g = randomize::get_rand(-16., 64.);
std::cout << g() << '\n';
// (5) integral template parameter within range [-infinity(short) ; infinity(short)]
std::cout << randomize::rand<short>() << '\n';
// (6) floating-point template parameter within range [-2 ; 3]
auto rand_double = randomize::rand<double, -2, 3>;
std::cout << rand_double() << '\n';
// (7) fill a vector with random numbers
std::vector<float> v(randomize::rand(5, 1'000));
std::generate(std::begin(v), std::end(v), randomize::get_rand(-100.f, 100.f));
std::copy(std::begin(v), std::end(v), std::ostream_iterator<float>(std::cout, " "));Possible output:
